ADJUSTMENTS
HUM BALANCE ADJUSTMENT - This adjustment minimizes
hum heard at the speakers. It is set at the factory, and
needs to be adjusted only if any of the smaller tubes, espe-
cially one of the 12AX7As, are replaced.
To make hum adjustment: with nothing plugged into the
amplifier, rotate the STEEL channel volume, middle, and
bass controls full clockwise. Rotate the GUITAR channel
treble control, and all the STEEL channel controls full
counter-clockwise. Turn REVERB and VIBRATO features off.
Insert a slotted screwdriver into the HUM BALANCE CON-
TROL (located on the bottom of the chassis) and rotate it
back and forth until you find the null (setting of minimum
hum). If you have any questions, consult your authorized
Fender Service Center.
BIAS ADJUSTMENT - This is a factory adjustment only.
Should the bias need adjusting, it should be performed by
your authorized Fender Service Center.

If the amp is set up but does not function, check the following items:
•
Is the amp power cord properly plugged into an electrical outlet?
•
Is there power at the outlet?
•
Is the fuse blown?
•
Is the speaker properly connected to the amplifier?
•
Is the amp on standby?
•
Are the amplifier volume and tone controls turned up above "three"?
•
Is the volume control on the instrument turned up?
•
Is your instrument properly plugged into the amplifier?
(Eliminate any effects pedals and try another guitar cord)
If, after checking all of the above, the system is not performing correctly,
consult your Fender Service Center.
TROUBLESHOOTER'S CHECKLIST
LINE CORD
Your amplifier is equipped with a grounding type supply
cord to reduce the possibility of shock due to electrical fault.
Be sure to connect it to a grounded receptacle.
DO NOT ALTER THE AC PLUG.
TUBES
The "CUSTOM" VIBRASONIC tube complement consists of
four Fender Special Design 6L6GCs (part number
023556), five Fender Special Design 12AX7As (part num-
ber 013341), and one Fender Special Design 12AT7 (part
number 023531). Fender's Special Design Tubes provide
optimum performance in this amplifier. For best results,
replace with Fender original equipment tubes only. Tube
location is printed on the tube label, inside the cabinet.
BLACK TOLEX COVERING CARE
The exclusive Fender Tolex covering on your cabinet is
especially designed to provide years of lasting beauty. A
very light soapy solution on a sponge may be used to
remove dirt and residue that may accumulate in the grain.
Be careful not to let any liquid come in contact with operat-
ing surfaces. DO NOT have the amplifier plugged into a
power outlet when cleaning.
